Seven signs worth recording
Droppings, gnawed packaging, rub marks, scratching sounds, nesting material, tracks and a direct sighting can all inform a rodent inspection. None should be used alone to distinguish rats from mice. Note which signs are new rather than assuming every mark indicates current activity.
Make an inspection record
Record the room, location and date. Photograph packaging damage and visible gaps without disturbing contaminated areas. Scratching may originate from another animal; an inspection should consider the building as well as the sound.
Look beyond the affected room
Shared waste stores, damaged external vents and routes around pipes can matter as much as a kitchen cupboard. Ask whether the survey includes communal areas and what permissions are needed for access.
